2. Description of the Related Art Generally, a window of a general house is provided with a shutter from the viewpoint of protection from wind and rain and crime prevention, and recently, a shutter-type structure that can be rolled up is often adopted. Is being done. This shutter shutter also serves as a substitute for the eaves of the shutter case, and is convenient for adjusting the lighting condition for the room.

Further, since the shutter mechanism which is the shutter for shutters is attached to the outer surface of the body above the opening,
It is suitable for installation in a place where there is no space for installing a shutter door bag on the side of the opening, and in particular, since it can be driven electrically, it can also be applied to home automation. On the other hand, recent homes have good airtightness, so it is rather necessary to ventilate indoors and outdoors.
This is an important point, and if this is not done enough, various problems will occur due to dew condensation or mold formation in the room.

In order to prevent this, a ventilation mechanism such as a compulsory ventilation fan is provided so that indoor and outdoor ventilation is performed, and a ventilation layer is formed in the housing structure itself. ing.

[Problems to be solved by the invention] However, considering the comfort of the living environment, artificially create it so that it fits the comfortable living life required by humans rather than the natural conditions. Is essential. Therefore, in the residence, to respond to each request,
Various kinds of equipment in which a motor for driving each device is incorporated are installed, for example, the shutter mechanism as described above and the ventilation mechanism.

[0006] However, these various types of housing equipment have nothing to do with other things, and they are independently installed. Considering the usage status of each device, its installation location, etc., space, There is a lot of waste in terms of equipment costs and other points. In view of this, the present invention focuses on commonality such as that the shutter mechanism and the ventilation mechanism are both installed near an opening such as a window as well as operated by a motor as described above. It was devised that the shutter mechanism and the ventilation mechanism can be selectively driven by switching the transmission path in the drive of one motor, and the installation space is reduced, and these It is an object of the present invention to provide a shutter with a ventilation function that can reduce the equipment cost for the.

[0007]

In order to achieve the above-mentioned object, according to the present invention, a shutter case installed on an outer surface of a body wall above an opening such as a window, and a shutter case arranged inside the shutter case. A slater that is wound up and pulled out by the drive of the motor through the shutter shaft, a ventilation fan that is rotated by the drive of the motor, and a switching unit that transmits the drive of the motor to the shutter shaft and / or the ventilation fan shaft. It is characterized by that.

Further, the ventilation fan can be attached inside the shutter case and the shutter case itself can be used as the ventilation passage, but it can be constructed by being arranged in the ventilation passage built in the shutter case.

[0009]

In the ventilated shutter according to the present invention, for example, the shutter is installed on the outer surface of the body wall above the opening such as a window in a general house. After the installation, the motor is driven by the driving force of the switching means. By selecting the transmission path, the ventilation fan in the ventilation mechanism is rotated to perform indoor / outdoor ventilation, and the shutter mechanism is used to wind the slatter and open / close the opening by pulling it out.

Further, the ventilation fan can be formed separately from the shutter case and installed adjacent to it, or can be built in the shutter case in advance. Also in this case, the shutter case itself may be provided inside the shutter case to serve as the ventilation passage, or the shutter case may be arranged inside the ventilation passage built in the shutter case.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the drawing indicates, for example, an opening O such as a window formed in the body wall W of a general house.
This is a shutter case attached to the upper outside, and in this shutter case 1, a slatter 2 that is rolled up and pulled out is flexibly connected and stored.

The slatter 2 is driven by a motor 3 built in the side of the shutter case 1, for example.
It is designed so that it can be wound and pulled out. Further, the ventilation fan 5 rotated by the drive of the same motor 3 is arranged in a ventilation path 6 penetrating the inside and outside of the body wall W. The motor 3 is driven by the switching means 10, 2
Depending on the selection by 0, it is possible to arbitrarily select and switch between the winding operation and the drawing operation of the slatter 2 and the ventilation operation of the ventilation fan 5.

The shutter case 1 has a length corresponding to the width of the opening O and is fixedly installed on the outer side surface of the body wall W above the opening O. The slater 2 is mounted around the supported shutter shaft 4 one time. Further, the motor 3 winds and pulls out the slatter 2 by rotating the shutter shaft 4 forward and backward through a speed reduction mechanism or the like. As shown in the drawing, the motor 3 is arranged and fixed to the lower part of the side of the shutter case 1. Moreover, the ventilation fan 5 is positioned so that it can be easily connected to a transmission mechanism for rotating the ventilation fan 5.

The ventilation passage 6 in which the ventilation fan 5 is arranged penetrates the skeleton wall W to communicate the inside and outside of the room.
The ventilation passage 6 shown in the figure has a substantially circular side surface so as to surround the outer periphery of the ventilation fan 5 having a multi-blade sirocco fan structure.
There is no substantially horizontal indoor-side ventilation part 8 connected to the through-cylinder 7 that is inserted through the body wall W, and the bottom side on the opposite side of the body wall W, which is the installation outside, is substantially vertical along the outside of the opening O. The outdoor side ventilation part 9 is formed.

The ventilation path 6 in the illustrated example, together with the ventilation fan 5 of the sirocco fan structure, is extremely effective in simplifying the drive transmission path of the motor 3 and simplifying the structure. Of course, the ventilation fan 5 itself may be any of exhaust, intake, and intake / exhaust type, and the ventilation fan 5 may have an axial center fan structure. It goes without saying that the shape of the ventilation path 6 and the structure of the transmission path for driving the motor 3 are different from those of the illustrated example.

The switching means 10 and 20 for selecting whether the slatter 2 is to be wound up or pulled out or the ventilation fan 5 to be operated for ventilation are constructed as shown in FIGS. 3 and 4, for example. The first switching means 10 shown in FIG. 3 outputs the drive of the motor 3 directly to the rotation operation of the ventilation fan 5 so that the output shaft of the motor 3 and the ventilation fan 5 can be transmitted.
The shaft is directly connected, and the clutch 11 is interposed between the ventilation fan 5 shaft and the shutter shaft 4.

According to the first switching means 10, the motor 3
To close the circuit, it is assumed that the ventilation fan 5 is constantly rotated to perform indoor / outdoor ventilation, and when necessary, by operating a switch (not shown) for instructing the presence or absence of a power transmission state in the clutch 11, Winding up Slater 2,
You can make a drawer. Also in this case,
The ventilation fan 5 always rotates when the slatter 2 is wound up and pulled out.

The second switching means 20 shown in FIG. 4 outputs the output of the motor 3 so as to directly and selectively actuate the drive of the motor 3 to the rotation operation of the ventilation fan 5 or the winding operation and the drawing operation of the slatter 2. A ventilation clutch 21 is interposed between one of the shafts and the ventilation fan 5 shaft, and a shutter clutch 22 is interposed between the other output shaft of the motor 3 and the shutter shaft 4.

According to the second switching means 20, the motor 3
After preparing for operation by closing the circuit, by operating a switch (not shown) for instructing the presence / absence of power transmission in any one of the clutches 21 and 22, ventilation of the ventilation fan 5 or hoisting of the slatter 2 is performed. , Can be pulled out, and at the same time, these can be done at the same time.

In the embodiment of the present invention constructed as described above, it is installed on the outer surface of the body wall W above the opening O such as a window in a general house. After the installation, the motor 3 is driven by rotating the ventilation fan 5 to perform indoor / outdoor ventilation by selecting a transmission system path for the driving force, and opening the slatter 2 by winding and drawing. The opening and closing action of the part O can be performed. At this time, when the first switching means 10 is provided, the slatter 2
The ventilation fan 5 can always be rotated regardless of the winding operation and the drawing operation of the fan. When the second switching unit 20 is provided, the rotation of the ventilation fan 5, the winding of the slatter 2, and the drawing operation can be arbitrarily performed. It can be performed in combination.

[0021]

The present invention is configured as described above, and therefore, by switching the drive transmission path of one motor installed internally, winding or pulling out of the slatter in the shutter mechanism, or You can select the operation of the ventilation fan in the ventilation mechanism that ventilates indoors and outdoors, and reduce the installation space,
In addition, equipment costs for these can be reduced.

That is, this is because the present invention is provided with a shutter case, a motor, a shutter mechanism, a ventilation mechanism, and a switching means, and these are integrally formed. This is because they are suitable for use as a crime prevention and can be installed in a state in which they are put together in an opening such as a window. Further, the ventilation fan can be formed separately from the shutter case and can be installed adjacent to it, or can be built in the shutter case in advance. Also in this case, the shutter case itself may be provided inside the shutter case to serve as the ventilation passage, or the shutter case may be arranged inside the ventilation passage built in the shutter case. If formed in this way, the whole structure can be made more compact and the ease of installation can be obtained.

Since there is only one motor for operating each of the shutter mechanism and the ventilation mechanism, it is not necessary to individually connect a circuit to each of them, which simplifies equipment construction and facilitates maintenance and inspection. Therefore, there is an advantage that the operating cost can be reduced.
